Abstract: A generally spherical body having a cluster of facets produced by truncation of the sphere, used for agitating and stirring solid foodstuffs in powdered form with liquid foodstuffs within a container. The removal of material to create the facets unbalances the stirring object, so that it gyrates unpredictably to produce a high degree of mixing turbulence. The facets further collide and slide together to help grind agglomerated lumps of the solid material within the mix. The stirrers have no nooks and crannies for deposit of foodstuffs, and so are easily washed and cleaned for subsequent uses. In one version, the body is of dense homogeneous material such as steel. In another version, the body has a dense object such as of steel embedded within a hard durable plastic outer portion carrying the abovementioned facets.
